The Problems Today there are no tools that help in writing correct models Most of them are visualization tools (e.g. Visual Paradigm) They do not try to analyze the model semantically One can create an inconsistent/redundant/infinite models using them

The Problems (Cont.) The same problem existed in the code world - one can:  use an uninitialized variable  leave a variable/method unused  render code unreachable Most of today’s IDEs support detection of these problems using static analysis tools

Existing Modeling Tools Static Modeling Tools: Visual Paradigm Eclipse (UML2 Tools) USE (a tool that provides evaluation of object diagram given a class diagram and OCL) Allows: designing and visualizing a UML model validating instances of the model using OCL Generating code from UML (and vice versa) but not analysis and reasoning about the model

Project Requirements Recognition of finite satisfiability problems in UML class diagram and detection of the constraints that cause them Suggesting implementation ways for a given Class Diagram Identifying inconsistency patterns - contradictory generalization set constraints. for instance: diamond class hierarchy

Project Requirements (Cont.) Ability to add new model based algorithms easily, schedule them and support their different outputs (e.g. generated report, markers on model elements) Identifying an opportunity to use a known Design Pattern Suggesting known refactoring when appropriate Transforming a Class Diagram into a State Machine when possible

Tools (model-based algorithms included) UML 2 ToolsUML 2 (meta-model)EMF Solution Abstract The Eclipse Modeling Framework (EMF) project is a modeling framework for building tools and other applications based on a structured data model. Framework

Solution Abstract (Cont.) We will develop an Eclipse plug-in which: provides a framework for running model tools provides a set of: static analysis tools, refactoring tools, validation and reasoning algorithms integrates the tools with the IDE
